- 8 Claims.

This invention relates generally to lamps for motor vehicles and constitutes a division of our application flied March Ill, 1937, hearing Serial No. 133,666.

One of the essential objects of theinvention is to provide a lamp of the type mentioned wherein approximately one-half of the housing is a die casting that is adapted to be mounted upon a suitable support such as a fender or radiator of a motor vehicle and is'provided with means for carrying the other elements of the housing including a sheet metal cover and a bezel. 4

Another object is to provide a lamp wherein a hermetically-sealed light unit is provided with an adjustable mounting carried by the die casting and bezel.

Another object is to provide a lamp wherein the bezel has a lower section integral with the die casting and has a separate'upper section that 20 is detachably fastened to the lower section to i'acilitate removal and replacement of the fluted and prismed lens.

Another object is to provide a lamp that is comparatively inexpensive to manufacture and install, and wherein the mounting means for the hermetically-sealed unit is simple in construction, readily accessible and easily adjusted as desired.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein:

Figure l is a bottom plan view of a lamp embodylng our invention;

Figure 2 is a front elevation of the structure lllustrated in Figure 1;

Figure 3 is a sectional view taken approximately on the lineI-I of Figure 2;

Figure 4 is a sectional view taken substantially on the line 4-4 of Figure 3;

Figure 5 is a sectional view taken substantially on the line l-I of Figure 2.

Referring now to the drawing. A is a lamp housing having a die cast base section i, a sheet metal cover I, and a bezel I. As shown, the base section i forms approximately the lower half of the housing and is provided at its forward end with a supporting portion 4 for the bezel. Preferably the cover section I is formed of sheet metal of inverted trough configuration and has its lower edges seated within a suitable groove or channel I in the upper edges of the'base section i. Any suitable means such as the bracket! and screw I may be employed for fastening the (GI. also-41s) cover I to the die casting I. As shown, the bracket I is fixed to the bottom I of the casting I, while the screw I extends through a suitable opening I in the cover I and threadedly engages said'bracket. Likewise, any suitable means (not shown) may be engaged with the bottom I of the casting i for mounting purposes.

of a hermetically-sealed unit I containing a lilament i0 and having a lens ii and reflector iI at the front and rear thereof. However. if desired, an open reflector and one or more bulbs carried thereby (not shown) may be used instead. In either case the lighting element would be provided' with an adjustable mounting II. As shown, this adjustable mounting is carried by lugs i4 and II integral with the base section i' The lighting element is preferably in the form v lugs. Coil springs II are sleeved upon the screws I II between the ring II and the lugs l4 and II, respectively, to hold the ring in proper position relative to the lugs according to the adjustment of the screws III. A screw II tapped in the bezel I extends through the ring II and engages an adjusting nut I4 on the back of the ring, while a.

coiled spring II is sleeved upon the screw II between the ring iI and bezel I.

In the present instance the supporting portion 4 of the bezel is integral with the base section i, but has a separate upper section II that is fastened by screws IT to the lower section 4. The fluted prismed lens I! flts within the bezel and has an annular flange II that fits within an annular groove II in said bezel. II is a channel gasket in the groove II receiving the edges of the flange II.

If desired, a bead Ii may be provided integral with the base section i at the upper edges thereof for overlapping the lower edges of the cover section I and may be covered by a chromium plated sheet metal bead (not shown).

Thus, with this construction the light projected from the unit I may be directed or aimed lower section of said casing, a supporting ring in the casing adjacent said lug and bezel, a seat for said unit carried by said ring, and means adjustably connecting said ring to said lug and bezel.

2. In a lamp structure, an ovoid casing split longitudinally substantially along a horizontal plane axially of the lamp and provided at one end with a sectional bezel, one section of said bezel being integral with one section of said casing, the second section of said bezel being separate from the casing and detachably connected to the first mentioned section of the bezel, a light unit in said casing, and a mounting for said unit including a lug on one sectionof said casing, a supporting ring in said casing adjacent said lug and bezel, a seat for said unit carried by said ring, and means adjustably connecting said ring to said lug and to one section of said bezel. 3. In a lamp structure, an ovoid casing split longitudinally substantially along a horizontal plane axially of the lampand provided at one end with a bezel, the lower section of said casing being attachable to a support, the upper section of said casing being mounted on said lower section and bezel, a light unit in said casing, and a mounting for said unit including a lug on the lower section of said casing, and a holder for said unit suspended from said bezel and adjustably connected to said lug.

4. In a lamp structure, an ovoid casing split longitudinally substantially along a-horizontal plane axially of the lamp and provided at one end with a sectional bezel, one section of said bezel being-integral with one section of said casing, the second section or said bezel being separate from the casing and detachably connected to the first mentioned section of the bezel, a light unit in said casing, and a mounting for said unit including alug on one section of said casing, and a holder for said unit suspended from the second section of said bezel and adjustably connected to said lug.

5. In a lamp structure, a casing provided at one '-"'end 'with a sectional bezel, one section of said bezel being integral with said casing, the second section of said bezel being separate from the casing and detachably connected to the first mentioned section oi. the bezel, a light unit in said casing, and a mounting for said unit including a lug within and rigid with a part of said casing, a supporting ring extending transversely of said casing and adjustably connected to said lug and second section of the bezel, and a seat for said unit carried by said ring.

6. In a lamp structure, a casing provided at one end with a bezel, a light unit in said casing, and a mounting for said unit including a lug projecting from the inside of said casing, a supporting holder for said unit having attaching portions at spaced points thereof, a screw projecting from the bezel through one of said attaching portions, an adjusting nut on said screw for urging the holder toward'the bezel, spring means on the screw between the holder and bezel, a screw pro- Jecting from another of said attaching portions and adiustably engaging said lug, an adjusting nut on the second mentioned screw engageable with the lug to urge the holder away from said bezel, and spring means on the second mentioned screw between the holder and lug.
